Christmas hypo

Has it been 100% proven that christmas sits on the hypo locus?

If so, is it known how christmas reacts with hypo and strawberry (ie. recessive, codom or dominant?)

According to the 2011 Cornsnake Morph Guide, it has been proven that the Christmas gene sits at the hypo A locus. As for how it works, what I can infer from what is written in the guide, it acts similarly to strawberry in that the phenotype varies with what gene it is expressed with. I'm not sure if it has any affect when only het with wild type so I would strictly call it recessive at this time.

I've bred my Christmas hypo to a granite, to give het Christmas/anery/diffused offspring, and also with a Love okeetee. I plan to breed him to a diffused het amel next year

so christmas/hypo and christmas/strawberry are different phenotypes to hypo, strawberry and hypo/strawberry (however minute the visual difference to the naked eye may be)?

Yep, and under the microscope the pigment cells look different too. This is my Christmas hypo, Lola

Here is My Christmas Hypo! His name is Typhoon.

They are gorgeous, loving how intense the colours are , and thanks for the info too I'm starting an update to the guide on Ians Vivarium so keep an eye out for the new pages

At some point I should try to get some good natural light photos of Lola. With the flash the deep cherry red of his saddles isn't shown.

that would be great, thank you. Theres no rush though, its going to be quite some time until the update is complete

No worries. I was over the moon Lola got 'in the vivarium'. His offspring are colouring up nicely too and hopefully next year I'll finally have Christmas bloods to show you!
